Comparative sequence analysis of IS50/Tn5 transposase
(American Society for Microbiology, 2004-12)
Comparative sequence analysis of IS50 transposase-related protein sequences in conjunction with known structural, biochemical, and genetic data was used to determine domains and residues that play key roles in IS50 ...
Exploring the relationship between sequence similarity and accurate phylogenetic trees
(Oxford University Press, 2006-08-04)
We have characterized the relationship between accurate phylogenetic reconstruction and sequence similarity, testing whether high levels of sequence similarity can consistently produce accurate evolutionary trees. We ...
Novel γ-carboxyglutamic acid-containing peptides from the venom of Conus textile
The cone snail is the only invertebrate system in which the vitamin K dependent carboxylase (or γ-carboxylase) and its product γ-carboxyglutamic acid (Gla)1 have been identified. It remains the sole source of ...
Odorant specificity of three oscillations and the DC signal in the turtle olfactory bulb
The odour-induced population response in the in vivo turtle (Terepene sp.) olfactory bulb consists of three oscillatory components (rostral, middle and caudal) that ride on top of a DC signal. In an initial step to determine ...
EGenBio : a data management system for evolutionary genomics and biodiversity
(BioMed Central, 2006-09-26)
EGenBio is a system for manipulation and filtering of large numbers of sequences, integrating curated sequence alignments and phylogenetic trees, managing evolutionary analyses, and visualizing their output. EGenBio is ...
Catecholaminergic connectivity to the inner ear, central auditory, and vocal motor circuitry in the plainfin midshipman fish porichthys notatus
Although the neuroanatomical distribution of catecholaminergic (CA) neurons has been well documented across all vertebrate classes, few studies have examined CA connectivity to physiologically and anatomically identified ...

Sewage reflects the microbiomes of human populations
(American Society for Microbiology, 2015-02-24)
Molecular characterizations of the gut microbiome from individual human stool samples have identified community patterns that correlate with age, disease, diet, and other human characteristics, but resources for marker ...
Farm management, not soil microbial diversity, controls nutrient loss from smallholder tropical agriculture
(Frontiers Media, 2015-03-04)
Tropical smallholder agriculture is undergoing rapid transformation in nutrient cycling pathways as international development efforts strongly promote greater use of mineral fertilizers to increase crop yields. These changes ...
Response of benthic metabolism and nutrient cycling to reductions in wastewater loading to Boston Harbor, USA
We describe the long-term response of benthic metabolism in depositional sediments of Boston Harbor, MA, to large reductions in organic matter and nutrient loading. Although Boston Harbor received very high loadings of ...
